Summary: This study investigated the use of ultrasound pretreatment to improve the encapsulation efficacy, solubility, and stability of a soybean protein isolate-luteolin nano-delivery system. The results demonstrated that ultrasound pretreatment enhanced the performance of the system, including increased loading amount and solubility, decreased particle size, and improved thermal stability. It also showed that ultrasound pretreatment increased the release rate and antioxidant activity of the nano-delivery system. This research provides preliminary evidence for the development of ultrasound pretreatment in the construction of protein-based nano-delivery systems.

Summary: The effects of high-intensity ultrasound (HIU) on the physicochemical and functional properties of insoluble potato protein isolates (ISPP) were investigated. The results showed that HIU treatment improved the solubility and emulsifying property of the proteins, but excessive treatment decreased their emulsification and gelling properties. Furthermore, HIU treatment also changed the secondary structure of the proteins, leading to the formation of a stable gel network.

Summary: This study aimed to investigate the influence of ultrasonic treatment on the physicochemical and antioxidant properties of mung bean protein hydrolysate (MPH). The results showed that ultrasonic treatment increased the contents of aromatic and hydrophobic amino acids in MPH, while decreasing the content of alpha-helix and increasing beta-sheet and beta-turn. Ultrasonic treatment also enhanced the antioxidant activities of MPH, making it a promising method to improve the antioxidant properties and broaden the application scope of MPH in the food industry.

Summary: This study investigated the ultrasonic degradation process, physicochemical properties, and prebiotic activity of ultrasonic degraded Flammulina velutipes polysaccharides (U-FVPs). The results showed that increasing ultrasonic intensity led to faster degradation, and reducing polysaccharide concentration contributed to degradation. Ultrasound changed the solution conformation and stability of the polysaccharide, resulting in decreased viscosity and gel strength but improved thermal stability. U-FVPs exhibited better prebiotic activity compared to the original polysaccharides.

Summary: The pull-in voltage is crucial in designing an optimal nano/micro-electromechanical system (N/MEMS). It is vital to have a simple formulation to calculate the pull-in voltage with relatively high accuracy. Two simple and effective methods are suggested for this purpose; one is an ancient Chinese algorithm and the other is an extension of He's frequency formulation.

Summary: In this work, a numerical approach based on shifted Legendre polynomials is proposed for solving fractional optimal control problems, utilizing the Atangana-Baleanu derivative for the derivative operation. The method combines operational matrices of AB-fractional integration and multiplication with the Lagrange multiplier method to simplify the problem into a system of nonlinear algebraic equations, resulting in an approximate solution with proven error estimate. Illustrative examples are used to demonstrate the accuracy and validity of the proposed scheme.

Summary: In this study, two different covalent reactions were compared to evaluate the strengthening effects of ultrasound treatment (UDT). The results showed that UDT destroyed the non-covalent interactions between myofibrillar protein (MPN) aggregates, and UDT-assisted free radical oxidation produced conjugates with better structural properties. After alkaline reaction, MPNs appeared as irregular spherical particles, while maintaining fibrous structure during free radical oxidation.

Summary: This study analyzed the perceived affective quality of indoor soundscapes among home workers during the COVID-19 lockdown, revealing differences in comfort, content, and soundscape appropriateness based on different activities. The study also highlighted associations between soundscape dimensions and psychological well-being, with various acoustical, building, urban, and person-related factors influencing soundscape dimensions and well-being in different ways. Notably, factors such as noise sensitivity and the number of people at home were found to have a negative impact on both comfort and well-being, partially explaining the link between comfortable indoor soundscapes and better mental health.

Summary: This work focuses on exploring the free vibration mechanism of plates with complex holes and cracks of arbitrary shape. A weak-form spectral element modeling approach is proposed and experimentally validated. By employing a flexible coordinate mapping strategy, the discontinuity problem of irregular holes and varying curvature cracks is effectively addressed. Modal experiments further confirm the excellent predictive capability of the spectral element methodology in vibration performance.

Summary: The main focus of this work is the comprehensive formularization of the frequency-amplitude formula, covering higher powers of the restoring force. Three equivalent styles of the generalized frequency amplitude have been proposed, along with the formulation of three forms of non-secular forces for the first time. These advances have been applied to the linearized Duffing oscillator, enriching the analysis and providing advantages for high nonlinearity vibration.
